The heights of 10 girls were measured in cm and the results are as follows: 135, 150, 139, 128, 151, 132, 146, 149, 143, 141. What is the range of the data?

Dear Student

First we have to arrange the given data in an ascending order,
= 128, 132, 135, 139, 141, 143, 146, 149, 150, 151
Range of given data = Tallest height–Shortest height
= 151–128
= 23 cm

Thanks
